The quality of transfer switch has crucial effect on the safe operation of on-loadvoltageregulation switch.
切换开关质量的好坏对能否保证有载调压开关的安全运行起着决定性的作用。

Based on guaranteeing reactive power equilibrium of the system, only the voltageregulation assisted by on - loadvoltageregulation can make the deviation of voltage keep in allowable scope.
在保证系统中无功功率平衡的基础上，辅以有载调压等措施调整电压，才可使电压的偏移保持在允许范围内。

To maintain both the voltage and the frequency within limits requires fine power control and loadregulation.
